“131 Share loss relief (1) An individual is eligible for relief under this Chapter (“share loss relief”) if— (a) the individual incurs an allowable loss for capital gains tax purposes on the disposal of any shares in any tax year (“the year of the loss”), and (b) the shares are qualifying shares. This is subject to subsections (3) and (4) and section 136(2). (2) – (4). 132 Entitlement to claim (1) An individual who is eligible for share loss relief may make a claim for the loss to be deducted in calculating the individual's net income— (a) for the year of the loss, (b) for the previous tax year, or (c) for both tax years. (See Step 2 of the calculation in section 23.) (2) If the claim is made in relation to both tax years, the claim must specify the year for which a deduction is to be made first. (3) Otherwise the claim must specify either the year of the loss or the previous tax year. (4) The claim must be made on or before the first anniversary of the normal self-assessment filing date for the year of the loss. 133 How relief works (1) This subsection explains how the deductions are to be made. The amount of the loss to be deducted at any step is limited in accordance with section 25(4) and (5). Step 1 Deduct the loss in calculating the individual's net income for the specified tax year. Step 2 This step applies only if the claim is made in relation to both tax years. Deduct the part of the loss not deducted at Step 1 in calculating the individual's net income for the other tax year. (2) Subsection (1) is subject to sections 136(5) and 147 (which set limits on the amounts of share loss relief that may be obtained in particular cases). (3) If an individual— (a) makes a claim for share loss relief against income (“the first claim”) in relation to the year of the loss, and (b) makes a separate claim for share loss relief against income in respect of a loss made in the following tax year in relation to the same tax year as the first claim, priority is to be given to making deductions under the first claim. (4) Any share loss relief claimed in respect of any income has priority over any relief claimed in respect of that income under section 64 (deduction of losses from general income) or 72 (early trade losses relief). (5) A claim for share loss relief does not affect any claim for a deduction under TCGA 1992 for so much of the allowable loss as is not deducted under subsection (1).”

“The word “return” may have a wider meaning in other contexts within the 1970 Act. But, in my view, in the context of sections 8(1), 9, 9A and 42(11)(a) of the 1970 Act, a “return” refers to the information in the tax return form which is submitted for “the purpose of establishing the amounts in which a person is chargeable to income tax and capital gains tax” for the relevant year of assessment and “the amount payable by him by way of income tax for that year”: section 8(1) the 1970 Act, as substituted firstly bysection 178(1) of the Finance Act 1994 and then further amended bysection 121(1) of the Finance Act 1996 and by section 114 of and Schedule 27 to theFinance Act 2007 .”
